Research on Optimal Reduction Program of River Basin by Multiple River Pollution Discharge

Abstract

In this paper, based on the process of multiple river pollution discharge simulation, the optimal method for reduction program is proposed for the pollution control. The four main rivers in Jiangsu province, China are selected for reducing the environmental pollution in nearshore district. Dissolved inorganic nitrogen (DIN) is studied as the only pollutant. As the max allowable emission amount is calculated by optimal numerical methods, the industrial, agriculture and domestic pollution source among the river basin will be found and reduced for the reduction program and environmental object. The research results of reduction program are the basis of marine environmental management.
